K6-2 450, Athlon XP 2000+, Sempron 3000+, Sempron 64 3400+, AMD Athlon X2 4400+, AMD Phenom II X2 550. That is my AMD heritage and this is an over-analyzed review of the i7s. I've been wanting to give sig rig to my father (Socket A Athlon XP 3000+) and move up to the 8150. Despite the lackluster results, I figured the new instruction sets, thread optimizations (Win 8) and overclockability would make up for it. I truly wanted to believe and tried to justify the purchase any way I could. The most helpful review I found was one I found on Hardcoreware.net, specifically the page on OpenCL performance and on Audio/Video Performance since those are two little extras I feel that I'd like to have available. Important features to me are gaming performance, folding/crunching, video editing and encoding, file compression/decompression, having all the fancy features/instruction sets, being "future-proof" and a having a generally nice price/performance (value) in all categories. Just so I didn't feel like I was missing anything, I started comparing features to similarly priced Intel products. I was surprised to find the Z68 boards were about the same price as 990FX boards and that they featured things like PCIe 3.0 and UEFI (which satisfies "future-proof" and geeky bragging). General questions: Is there any difference between the 2600k and the 2700k besides 100Mhz and a price bump? Is overclocking generally pretty straightforward like it is for AMD? The difference between the 2500k and 2600k is HyperThreading (and MHz), correct? Will I see any more than 20-30% increase per clock than I've found in the charts below? If the 2600k isn't that much better than the 2500k, am I an idiot for wanting one anyways? It feels more future-proof and appeals to my wanting as many cores as possible (even if they're just HT). Any tips and tricks I should know before buying? Should I go for the 1100t and wait for Ivy Bridge? Price options: X6 1100t and mid-range AM3 board: ~$250 Would give me a processor that should sell easily if I decide to upgrade later, but makes me uncomfortable in the sense that it's a rather temporary fix. Fits in to my lackluster budget. FX 8150 and 990FX: ~$445 The processor I wish was either faster or cheaper. Features are mostly there, price/performance (value) isn't. If the 6GHz average OC is true, this would give the best performance out of the bunch. Reviewers are saying 5GHz on water. That's enough to make the FX a bit competitive. 2500k and Z68: ~$400 Cheaper than the FX 8150, generally faster, but lacks the future-proof comfort I get from the 2600k's HyperThreading. 2600k and Z68: ~$510 Feels like it would last longer. Feels more "comfortable" from a hardware standpoint, but it's a bit more than I want to spend. I would expect closer to $450. The processor alone costs 53% more for 30% more performance, but if you include the motherboard in the price, it only costs 28% more (which sits right with the 20-30% performance increase). I've made a rough chart comparing price/performance, efficiency, etc. I should note that most 2700k benchmarks are estimates based off of a 100MHz bump and that the price/performance for the 1100T is based off of an $80 motherboard since I would most likely reuse my 790FX and buy a cheap mobo for my X2.

Estimated motherboard prices: X6 1100t: $80 (Mid-range board) FX 8150: $175 (Asus something-or-other) 2500k: $190 (Asus P8Z68-V/GEN3) 2600k: $190 (Asus P8Z68-V/GEN3) To-Do: Add $100 to total price in overclocked section (for cheap watercooling kit).
